ZEN V2 Units

Even Broader Applications with Increased

Functionality and Higher Precision

• Increased functionality in a compact body (70 mm wide × 90 mm

high).

• Easy programming is available using the LCD and operation

buttons. (See note 1.)

• This single Unit easily provides relay, timer, counter, and time

switch functions.

• Expansion is easy with Expansion I/O Units, allowing up to 44

I/O points. (See note 2.)

• Economy-type and Communications-type CPU Units have been

added to series.

• Improved Weekly Timers (See note 1.)

Increased timing accuracy with a monthly deviation of ±15 s

max. Multiple-day operation and pulse output operation have

been added.

• Select from two power supply options:

100 to 240 VAC or 12 to 24 VDC.

Features

■ Easy and Simple Programming for Automatic Small-scale Control

Saves Space, Wiring, and Installation Steps

• Versatile functionality in a compact body (70 mm wide × 90 mm

high).

• This single Unit easily provides relay, timer, counter, and time

switch functions. Wiring work is greatly reduced because separate

wiring is not required for devices such as timers and counters.

Easy Programming

The LCD screen comes with 8 operation buttons on the front panel to

enable programming in ladder view format. The LCD screen also has

a backlight, making it easier to see when the ZEN is used in dark

locations.

Note: Not supported for ZEN-@C2@@-@-V2 models.

ZEN V2 Units Units with DC Power Supply Note: 1. Be sure to connect the COM terminal before turning ON the power supply. If the COM terminal is disconnected, or if the wiring is changed after turning ON the power supply, a malfunction may occur. 2. Apply the power supply voltage through a relay or switch in such a way that the voltage reaches the rated value within 4 s. If the voltage is applied gradually, the power may not be reset or unstable output operations may result.

ZEN V2 Units 4. Counter Operation The counter bit turns ON when the counter value (present value) reaches the set value (present value ≥ set value). The counter returns to 0 and the counter bit turns OFF when the reset input turns ON. Count inputs are not accepted while the reset input is turned ON. The counter present value and counter bit (ON/OFF) are held even if the operating mode is changed or the power supply is interrupted.

ZEN V2 Units Precautions when Switching from Previous Units • • • • Previous models of Expansion I/O Units cannot be connected to V2 CPU Units. ZEN-8E1@R Expansion I/O Units with relay outputs need to be connected to a power supply. A ZEN-@C@D@-D-V2 CPU Unit with DC power supply cannot be connected to an Expansion I/O Unit with AC inputs. When connecting Expansion I/O Units with DC inputs to a CPU Unit with an AC power supply, the burst noise immunity will be 1 kV (IEC 610004-4).
